Perfect size and fit

This sandal is the perfect fit and very comfy. It’s very sturdy and outdoor friendly as well. I love how flexible and breathable this is and the design makes it even more perfect.

Great...
Size: 8 Women/7 Men, Color: Black/Black/Black
I bought these flip-flops, and they exceeded my expectations. The highlights for me are: Total Comfort: They are extremely comfortable right from day one. Great Quality: You can tell the materials are sturdy and durable—typical of the brand. Excellent Price: Unbeatable value for money. I really liked them; it’s undoubtedly a purchase you won't regret. They are totally worth it!

VERY SMALL but otherwise perfect
Size: 9 Women/8 Men, Color: Black/White/Black
okay so one of my feet is slightly larger than the other, only like a quarter maybe half size, making shoe shopping difficult sometimes.. not often bc with sneakers and other closed toe shoes, it’s not usually a problem, it’s really only slides. anyway i’m a women’s 8.5 sometimes 9. if they only have whole sizes, 95% of the time I go with 9 and rarely an 8. i’ve never in my life bought shoes larger than a 9. it’s worth noting I recently bought two new adidas superstar sneakers in a 9 and I wear them when I want comfort bc they fit so well. that was maybe 6 months ago and I’m grown so they are not changing. I order the 9 (men’s 8/womens 9) and my left foot looks fine but the bigger foot is giving me pause. the shoes themselves were the exact length as my actual foot, leaving no room at the toe or heel, and my feet fit perfectly in the indentations of a foot.. but they just didn’t feel right. I walked around my carpet for a little bit and caught my toes hanging past the actual shoe and basically in mid air. At that moment I knew I needed to size up to a 10 which is crazy to me. The 10 got here today and fits much better, even though now it’s a little big on my smaller foot, but not enough to cause a problem. I’m just shocked i’m wearing a size 10 bc im 40 years old.. lol i’ve been buying shoes for quite some time and never once in my life did I need to size up to a 10. Surprisingly the 10s aren’t noticeably bigger all around, like in the actual strap that holds your feet. I love these slides, always have, I just don’t ever remember having to buy a 10. Personally, I think it’s because of the unisex sizing- men’s and women’s shoes are more than one size different. It’s closer to a size and a half. my parents had a shoe store for like 15 years so I promise you I know what I’m talking about. anyway I would absolutely recommend sizing up one whole size unless you know for a fact what size you wear in these specific shoes.

Reliable comfortable stylish
Great product for the money.... Very solid!! Needs some breaking in but will definitely be more comfy after some weeks of consistent wear. Arch support is hard at first but once broken is feel nice. Great design and nice color way. Easy to keep clean. Would highly recommend. Great for house gym or light pool use.
